Blood type O is the primal blood type of our ancestors who were cunning, aggressive predators. It is often believed that their uniqueness comes from the fact that our ancestors were hunters who had to observe and accurately evaluate the environment to be able to survive.
According to experts, blood type O is the oldest blood group in human history. It has been traced to as far back as Cro-Magnon man, and its evolution can be dated to approximately 40,000 BC.
